[0022] The utility model provides an embodiment:

[0023] like Figures 1 to 4 As shown, a long-distance track cycling bicycle is used in underground coal mines, comprising a main structure, a front guide wheel 2, a side guide wheel 3 and a cargo box 4; the front guide wheel 2 and the side guide wheel 3 are respectively located at the main track and the side track, the front guide wheel 2 is connected to the front fork 6 of the main structure via the front guide wheel connecting rod 5, a rear wheel connecting rod 7 and a support frame 8 are arranged on the same side of the rear of the main structure, the two ends of the rear wheel connecting rod 7 are respectively connected to the rear lower fork 9 and the support frame 8 of the main structure, one end of the support frame 8 located at the front of the main structure is connected to the central axis of the front wheel 10 of the main structure, the cargo box 4 is detachably connected to the upper end of the support frame 8, the side guide wheel 3 is connected to the lower end of the cargo box 4 via the side fork structure 11, and the front wheel 10 and the rear wheel 13 of the main structure are both located on the main track.

[0024] In this embodiment, the main structure includes a front wheel 10, a rear wheel 13, a flywheel 16, a front fork 6, a rear lower fork 9, a rear upper fork 17, a chain, a toothed disc 18, a foot pedal 19, a tripod 20, a seat 21, a handlebar 22 and a headlight 12. The parameters of the mining rails involved are rail height, rail bottom width, rail top width, waist thickness and track gauge. The rail height used this time is 44mm; the ratio of rail bottom width to rail height is 1:1.67, and the selected rail bottom width is 26mm; the ratio of rail top width to rail height is usually 1:1.1, and the selected rail top width is 40mm; the waist thickness is usually 1 / 2 of the rail height, and the selected rail waist is 22mm; the size of the track gauge selected this time is 600mm.

[0025] The underground track carries the main structure of the bicycle on one side and connects the guide wheel on the other side. The main structure and the side guide wheel are connected in a triangular structure. All wheels are made of Q235B carbon structural steel, which has good mechanical properties, elongation, strength, good toughness and tightness. The diameter of the two main wheels of the track bicycle is φ660mm, the width is 40mm, and the thickness is 5mm; the front wheel is connected to the two front guide wheels, the front guide wheel has a diameter of φ120mm, a width of 20mm, and a thickness of 3mm; the side wheel has a diameter of φ200mm, a width of 40mm, and a thickness of 3mm.

[0026] The support frame 8 is an isosceles triangle support device. The triangle device has strong stability and is stable and pressure-resistant. The device uses Q235B carbon structural steel with an angle of 43° (the angle can be adjusted according to the track gauge selected by the specific mine). Because the track gauge selected for this structure is 600mm, it can be calculated that the left slash is 844mm and the right slash is 885mm. The triangular support device can hold a cargo box with a length of 1100mm, a width of 250mm, and a height of 300mm, which can transport some larger tools or equipment, such as drilling rigs, compressors, maintenance tools, etc. In addition, the cargo box can also be disassembled at any time. A plurality of groove structures are arranged on the support frame 8, and a protrusion matching the position of the groove structure is arranged at the lower end of the cargo box 4.

[0027] The rear wheel connecting rod 7 is parallel to the track surface, and one end of the rear wheel connecting rod 7 is connected to the rear lower fork 9 through a docking fastener 15; the support frame 8 includes two support pipes at an angle, and the ends of the support pipes are fixedly connected with a disc-shaped structure 1, and holes are set on the disc-shaped structure. The disc-shaped structure of one support pipe is locked on the rear wheel connecting rod 7 by bolts and nuts, and the disc-shaped structure of the other support pipe is sleeved on the center axis of the front wheel 10 and locked by nuts to ensure the smooth operation of the bicycle and prevent the bicycle from derailing. The support pipe is cold-bent, and a mechanical or manual tool is used to apply force at the appropriate position to make the steel pipe begin to bend. After bending and forming, the steel pipe maintains the inherent ductility of the plate to avoid subsequent deformation. The bent steel pipe is parallel to the front wheel, and a hole of the same size as the center axis of the bicycle is punched on the steel pipe, and it is fixed with bolts and nuts. The side fork structure 11 includes a fork-shaped structure connected to the side guide wheel 3 and a vertical rod connected to the top of the support frame 8, and the vertical rod is fixed to the upper end of the fork-shaped structure.

[0028] There is a front guide wheel cross bar 14 rotatably connected between the two front guide wheels 2. The front guide wheel cross bar 14 is rollingly connected to the main track and the inner sides of the two front guide wheels 2 are both fitted to the outer edge of the main track. The upper end of the front guide wheel connecting rod 5 is connected to the front fork 6 through a docking fastener 15. The docking fastener 15 includes two rotatably connected tubular fasteners, one of which is fastened to the lower part of the front fork 6, and the other is fastened to the upper part of the front guide wheel connecting rod 5. The docking fastener is composed of two sub-fasteners. The small end of the lower fastener in each sub-fastener is connected to a movable bolt, and the fastener has the advantages of strong corrosion resistance, strong anti-detachment ability, and strong anti-deformation ability. There is a bearing device inside the front guide wheel. The bearing device is a rolling bearing with matching dimensions. In order to ensure that the bearing works smoothly and reliably, lubricating oil needs to be added for lubrication, in order to reduce internal friction and wear of the bearing. The two front guide wheels are close to the edge of the track but do not contact the track. The two front guide wheels on both sides of the track can prevent the front wheel of the bicycle from derailing, so that the front guide wheel cross bar rolls on the track to ensure the smooth operation of the bicycle.

[0029] The docking fasteners designed in this invention are easy to disassemble. When no one is using the bicycle underground, the support frame 8, the front guide wheel connecting rod-guide wheel device and the bicycle can be disassembled. The cargo box and the support frame 8 are also detachable devices, which are easy to carry. When not in use, they can be placed on both sides of the tunnel to avoid obstructing the transportation of ore and waste rock and other large equipment and special equipment by trucks.

[0030] The above is only a preferred specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by any technician familiar with the technical field within the technical scope disclosed by the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model shall be based on the protection scope of the claims.
